WHEAT-SOWING .MACHINE.

SPECIFICATION forming part of Letters Patent No. 284,376,dated'september 4, 1883. Application filed April 20, 1883. (No model.)

To all whom. it may concern:

Be it known thatl, CYRUS O. CARTER, of Neelyville, in the county of Morgan and State of Illinois, have invented certain new and use ful Improvements in Wheat-SowingMachines, of which the following is a specification, ref erence being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention is, designedto. allow of the simultaneous lifting or depressing of the runners through which the seed-tubes extend from the seed-box, whereby the seed may be deposited at the required depth in the ground; also, to allow the machine to be converted from a drill to a broadcast sower; and it consists in details of construction and combinations of parts, as hereinafter specified.

In the drawings, Figure 1 is a vertical sec tion of the machine. Fig. 2 is a plan view of thesame.

Similar letters of reference indicate similar parts in both views.

A is theframe of the machine, mounted on wheels A. To the front of the frame the ordinary draft-tongue, a, is secured.

B is the seed-box, elevated on standards b above the frame of the machine.

O C, &c., are runners pivoted or hung to the frame, as shown, their free ends being adapted to rest upon or belowthe surface of the ground, or to be liftedabove said surface, beingguided by the notched heel-piece G,-secured to the frame A. l

D is a shaft, also pivoted or mounted upon the frame, as shown, to which shaft a series of platesprings, c, are attached, extending to the upper parts of the runners 0, connection being made betweenthe springs and the'runners by the springs projecting between transverse pins cl, which span the opening formed insaid upper parts. of the runners.

To the front of the shaft D is pivoted a handlever, E provided with a plate, f.

. F is a segmental notched plate extending from the front of the frameA to the under side of the seed-box. The plate f projects from the side of the lever, and can be made to enter any one of the notches g of the 'segmentalplate F, it being necessary to move the lever E upon its pivot, so as to draw the plate f from one notch before it can I be placed in another by again pushing thel'ever toward the plate.' It will thus be seen that the entire series of runners can be lifted by the single action of the lever and adjusted to any required depth below or above the surface of the earth; The back or free, ends of the runners are curved concentrically with the pivot on which the runners move. The heel-piece O prevents their lateral movement. I

To the inner side of the standards I) are secured horizontal supports h, on which a sliding board, 2', carrying the seed-tubes 7c, rests.

The seed-tubes k pass downward through open- 6 ings formed in the runners, which openings are large enough to allow the runners to be moved up or down without interfering with the tubes. The rear. part, i, of the sliding board is inclined outward and downward, as

shown. The bottom of the seed-box is elevated a short distance abovethe sliding board 13 and is perforated. The seed-box is provided with a sliding valve perforated to register with the perforated floor of theseed-box, so thatby moving thevalve either the entireperforated area of the floor of the seed-box may be uncovered or only a part thereof, and the flow of seed to the tubes regulated. WVhen the machine is to be used as a drill, the upper end of be pushed inward until the tubes are out of the range of the openings in the floor of theseedbox, whereupon the seed will fall from the seed-boxto the top of the board Land thence to the part i of the board broadcast to the earth.

The seed within the seed-box is agitated by 0 means of a shaft, Z,ha'ving agitators Z,the shaft being operatedthrough the medium of armsm and rods 1, the latter having each a crank-connection with one of the wheels A. I

The operation of the machine will be appar- 5 ent from the foregoing description, the series of runners O, 810., being lowered the required depth in the ground, conveying the seed into the ground from the seed-box through the seedtubes. The runners are conveniently elevated, IOO

depressed, or secured as a series by means of the lever E and segmental notched plate F and the lever-platef. The heel-piece O is an important feature and maintains the entire series of runners in proper position. The springs 0 will yield, so as to prevent the jarring of the machine, should any of the runners strike an obstruction.

The means employed for converting the machine from a drill to a broadcast sower are simple and effective.

7 I claim as my invention- 1. The combination, in a wheat-sowing machine, of a series of runners pivoted or hung' to the frame, a notched heel-piece in which the free ends of the runners rest, ahand-lever pivoted to'a shaft journ'aled in the frame, and a series of horizontal plate-springs projecting from said shaft and connecting with the free ends of the-runners, substantially as set forth.

2. A shaft j ournaled in the frame, and a handlever pivoted thereto and adaptedto be moved transversely on its pivot of the frame, and having a catch-plate, combined with a notched segment, substantially as set forth.

3. A runner having its rear end curved concentrically with its pivot and provided with an opening forthe seed-tube, combined with a notched heel-piece, and a horizontal platespring connecting the free end of the runner with a transverse rotative shaft, substantially as set forth.

4. The combination, with the seed-box, of the sliding board 7;, provided with the inclined plane '5, and having flexible seed-tubes connected therewith, substantially as set forth.

In testimony hereof I hereunto set my hand :7, 5 and seal this 3d day of April, 1883. 7
